Description

Technical Field

[0001] The invention belongs to the technical field of high voltage chamber environment control, and in particular relates to a high voltage chamber environment control device for a transformer substation capacitor and a control method thereof. Background Art

[0002] Insulation partitions or insulation sheaths are usually installed in the high-voltage room of the substation to reduce the safety hazards of the high-voltage room. However, insulation breakdown failures still occur frequently. Most insulation breakdowns of switch cabinets are caused by three key factors: temperature, humidity and dirt. When the high-voltage room is poorly sealed from the outside world, outdoor moisture and dust will enter the switch cabinet, causing the insulation parts to become damp and dirty, thereby reducing the insulation strength and causing flashover breakdown failures. In severe cases, it will cause the busbar to stop completely, the transformer outlet to short-circuit, and even the entire switch cabinet to burn out.
